The correct answer is "صح" which means "true" in Arabic. This suggests that the majority of monosaccharides are of a certain type. However, without further context or information, it is not possible to determine the specific type of monosaccharides being referred to in this question.

The given statement is correct because cellulose is a complex carbohydrate that is composed of glucose molecules. It is a structural component of plant cell walls and provides rigidity and support to plant cells. Cellulose is considered a polysaccharide, which is a type of complex sugar that is formed by the bonding of multiple sugar molecules. Therefore, it is accurate to say that cellulose is a structural sugar.

The explanation for the given correct answer is that the statement is stating that the bond formed between two monosaccharides to form a disaccharide is called a glycosidic bond. This is a type of covalent bond that joins the two monosaccharides together, resulting in the formation of a disaccharide.

The molecular formula of glucose is C6H12O6. Each carbon atom in the molecule can exist in a different spatial arrangement, resulting in different stereoisomers. Glucose has 16 stereoisomers because there are 4 chiral carbon atoms in the molecule, and each chiral carbon can have 2 possible configurations (R or S). Therefore, the total number of stereoisomers is 2^4 = 16.
